发展中国家的电力市场化改革综述——市场模式、约束条件及路径选择

发展中国家由于社会和经济发展水平低,在电力市场化改革中遇到了很多教训。电力市场的目标模式是零售竞争型、但发展中国家受制度、资本市场、人力资源、技术的约束,难以直接实现目标模式。渐进式改革路径更适用于发展中国家的电力市场化改革。     

在进一步解放思想中深化改革

纵观世界历史,人类社会的进步总是由思想解放引领的。从思想的形成过程和人类自身的认知规律来看,人的思想总是会受到“内因”和“外因”的束缚,因此,需要打破阻碍或束缚人们准确认识客观现实的各种藩篱,使思想和实际相符合,使主观和客观相一致。中国四十年的改革开放史就是一部思想解放史。因为实现了“三个确立”,并且正在冲破“三个思维定势”,我们得以为中国经济起飞和持续发展提供不竭动力。进入新时代,解放思想必须实实在在地落到解决深层次问题上,需重点关注三个方面：一是推动中国理论体系发挥重大作用,二是完善符合中国实践的公平正义保障体系,三是发展构建命运共同体需要的新国际交往思维。     

股权制衡、非国有股东委派董事与公司绩效

从公司治理层面完善国有控股企业的股权制衡是国企混合所有制改革的重点和难点,以往学者仅仅研究了股权制衡与公司绩效之间的关系,很少研究两者关系的作用路径和影响机理.因此,引入非国有股东委派董事这一概念,研究非国有股东委派董事在股权制衡与公司绩效之间发挥的中介效应.结果表明:股权制衡有利于公司绩效的提升,非国有股东委派董事在股权制衡与公司绩效两者之间发挥了中介效应.     

Internal Markets,Management by Targets,and Quasi‐Markets: An Analysis of Health Care Reforms in the English NHS

There have been two major attempts to introduce market mechanisms into England's National Health Service: the ‘internal market’ reform project of the 1990s, and the ‘quasi‐market’ of the 2000s. Despite their similarities, the former attempt was on balance unsuccessful while the latter succeeded. This article examines and compares the outcomes of the two periods, analysing the reasons for their relative successes and failures. It goes on to highlight options for future reforms that would build on those achievements.     

高职高专考试考核方式改革之探索

本文以宁夏工商职业技术学院机电工程系《典型电气控制设备的安装》考试考核方式改革为例,分析了传统的教学方法和教学内容已经不能适应人才培养的需要。怎样按职业教育的规律和特点培养出符合企业需要的人才是目前高职院校的头等大事,机电工程系经过多年的研究和实践,探索出了校企合作、工学结合的人才培养模式是在高等职业教育中一种非常有效的人才培养模式,而这种人才培养模式的实施,其关键在于教育教学的课程改革。由此引出了课程体系构建、教学内容选择、教材编写、双师素质教师的培养、教学环境建设、教学方法、考试考核方式改革和教学组织等一系列课题。     

收益率差异视角下股票流动性与资本结构关系的再检验

本文在股票收益率差异视角下，选择2000年1月到2015年12月期间中国沪、深市场307家上市公司数据，采用单方程估计法和联立方程组系统估计法研究我国上市公司股票流动性与资本结构的相互影响；并分别从股权分置改革、股权再融资、牛熊市行情三个方面对二者关系的变化与差异进行深入分析。结果表明：股票流动性与资本结构之间存在显著的负向关系，并且随着股票收益率水平的提高，负向影响越来越明显；股权分置改革后、满足再融资资格的上市公司以及牛市行情下两者的相互影响更显著。     

Population,pensions, and endogenous economic growth

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor productivity are more profitable. We incorporate this channel in a new dynamic general equilibrium model with endogenous economic growth and heterogeneous overlapping generations. We calibrate the model for the US economy and obtain the following results. First, the effect of a decline in population growth on labor productivity growth is positive and quantitatively significant. In our benchmark, it is predicted to increase from an average annual growth rate of 1.74% over 1990–2000 to 2.41% in 2100. Second, institutional characteristics of the pension system matter both for the growth performance and for individual welfare. Third, the assessment of pension reform proposals may depend on whether economic growth is endogenous or exogenous.     

Institutional plasticity in public-private interactions: Why Japan’s port reform failed

This study applies the concept of institutional plasticity to analyze institutional change, and investigates why actors are unable to change institutions even when change is apparently necessary. Employing historical institutionalism, the analysis focuses on public-private interactions in the recent port reform in Japan. The study’s findings reveal four limits to institutional plasticity due to the respective roles of key actors – the central government, the local port authority, and business entities – in the process of policy reform. The study suggests that while institutional plasticity may enable variation within an existing developmental trajectory or even creation of an entirely new path, insufficient institutional plasticity constrains the creation of new institutions and inhibits institutional change.     

供给侧结构性改革推进四川省玉米产业转型发展策略

[目的]随着中国粮食产量的"十二连增",国内农业生产的主要矛盾也逐步由总量不足转向结构性矛盾,其中玉米产业面临的矛盾尤为突出,玉米产业结构调整是我国农业供给侧结构性改革推进中的首要任务。四川既是全国玉米生产的重要省份,也是玉米消费大省,如何推进玉米产业供给侧结构性改革、实现产业转型发展还有待于思考。[方法]文章从供需平衡、供给结构、供给效益和供给效率4个角度分析了四川玉米产业供给侧的特征,同时从要素供给、社会化服务和产业链3个方面分析了影响四川玉米产业发展的制约因素。[结果]四川玉米消费结构呈现多元变化,从口粮消费为主转变为以饲料、工业加工消费为主;草食畜牧业发展迅速,饲用作物需求量增大;农业科技支撑力度明显,玉米育种成就突出。[结论]提出从优化品种结构、推行种养循环、培育新型经营主体、拓展产业链等方面推进四川玉米产业的转型升级。     

International spillovers of China's structural reforms

This paper sheds light on the international spillovers of China's reforms in upgrading industrial capabilities, liberalizing capital account, internationalizing the renminbi, and transition to flexible exchange rates. Drawing on two-country New Keynesian model of endogenous entry and portfolio adjustment, we find that China's industrial upgrading that peddles on yuan appreciation lifts all boats through global production network irrespective of capital account convertibility, degree of renminbi internationalization, and exchange rate reform. Feasibility of appreciation-driven upgrading is called into question, however, when renminbi reform and capital account liberalization go in parallel. We also show that international spillovers disappear once renminbi internationalization is associated with liberalized capital account and flexible renminbi exchange rates.
